Product Description

Product Description

-K Series Helical Bevel Gearbox
 

K series gear reducer, manufactured according to international technical requirements, has a high scientific and technological content; Space saving, reliable and durable, high overload capacity, power up to 132KW; Low energy consumption, superior performance, reducer efficiency up to 95%
It is designed and manufactured on the basis of module combination system. There are a lot of motor combinations, installation forms and structural schemes. The transmission ratio is classified carefully to meet different operating conditions and realize electromechanical integration.

High transmission efficiency, low energy consumption and superior performance.

Reinforced high rigid cast iron box; The hardened gear is made of high-quality alloy steel. Its surface is carburized, quenched and hardened, and the gear is finely ground. It features stable transmission, low noise, large bearing capacity, low temperature rise, and long service life. Performance and characteristics:

1. The gear is carburized and quenched with high-quality alloy, the hardness of the tooth surface is up to 60 ± 2hrc, and the grinding accuracy of the tooth surface is up to 5-6

2. The computer modification technology is used to pre modify the gear, which greatly improves the bearing capacity of the reducer

3. Complete modular structure design is adopted from the box to the internal gear, which is suitable for large-scale production and flexible selection

4. The standard reducer models are divided according to the form of decreasing torque. Compared with the traditional equal proportion division, they are more in line with customer requirements and avoid power waste

5. It is designed and manufactured by cad/cam to ensure the stability of quality

6. Multiple sealing structures are adopted to prevent oil leakage

7. Multi directional noise reduction measures to ensure the excellent low noise performance of the reducer

8. The installation mode of Liyi products is flexible, which makes it easy for customers to choose K57 reducer, K67 reducer, K77 reducer, K87 reducer, K97 reducer, KA87 reducer, KA97 reducer, KA107 reducer, KA127 reducer

Product Features
1. Input mode: Coupled motor, belted motor, input shaft or connection flange.
2. Output: Right angle
3. Compact structure. Rigid tooth face. Carrying greater torque, high loading capacity.
4.High precision gear, ensuring the unit to operate stably, smooth transmission.
5. Low noise, long lifespan. Large overlap coefficient, abrasion resistant.
